Final-ish comment on this:
Here are the valid workarounds to this issue:
- Turn off email validation and enable captchas (if doing open registration like I am)
- Turn on the registration from, and disable captchas.
- Fix your SMTP settings
- For anyone impacted by a failed registration, have them use a “plus” email address like ( theiruser+lemmy@somedomain.com ) after you have it fixed.
Done! Thanks for the reminder, I’m deep in trying to get users onboarded and such and probably would’ve forgot!
